我可以 Telnet 进入 Linux CentOS 系统,但无法通过 SSH 进入。我的同事说他们可以 SSH 进入

我的公司有一个服务器(服务器 A)在一家电信公司的数据中心。该服务器无法通过互联网访问。我需要访问该服务器,因为我正在开发一个服务器应用程序。

我们有第二台服务器(服务器 B)在同一个数据中心,我可以轻松 ssh 进入,我的同事也可以 ssh 和 telnet 进入(服务器 A)来自第二台服务器。

我也可以 telnet(服务器 A)(服务器 B),但我无法 ssh 进入(服务器 A)(服务器 B)

我如何通过 ssh 进入可以 telnet 的服务器?

ssh user@domain -p但之后仍然无法正常运作。

对此我深表歉意。我发现 Putty 通常会将界面挂在应该出现密码提示的位置,这很不妥。很抱歉打扰了大家,但这个问题已经重复出现好几天了,如果不是偶然,我永远也不会猜到。我的解决方案是继续调整页面大小并留在终端上。谢谢
